On Friday October 5th, timed to coincide with the 50th anniversary of the release of Dr. No, and the newly (and by no means modestly) declared Global James Bond Day, British singer Adele will release the official theme song to the upcoming James Bond film Skyfall via her official website www.Adele.tv at 9.07am AEST.

A 90 second section of the song has been leaked online allowing fans a taste of Friday's release.

Skyfall is the first recording by Adele since releasing her award winning album 21 in early 2011.

"I was a little hesitant at first to be involved with the theme song for Skyfall," Adele said in a statement.

"There's a lot of instant spotlight and pressure when it comes to a Bond song. But I fell in love with the script and Paul had some great ideas for the track and it ended up being a bit of a no brainer to do it in the end. It was also a lot of fun writing to a brief, something I've never done which made it exciting."

Co-written and produced by Paul Epworth, the theme song to Skyfall was recorded at Abbey Road Studios in London featuring a 77-piece orchestra accompaniment.

"When we recorded the strings, it was one of the proudest moments of my life. I’ll be back combing my hair when I'm 60 telling people I was a Bond girl back in the day I'm sure!”
